TAN K-VALVE.

SPECIFICATION forming part of Letters Patent No. 393,884, dated December4, 1888.

Application filed June 9, 1888. Serial No. 276,646. (No model.)

To all whom it may concern.-

Be it known that I, JAMES CAVANAGH, a citizen of the United States, anda resident of the city, county, and State of New York, have invented anew and useful Improvement in Tank-Valves, of which the followingdescription, in connection with the acconmauying drawings, is aspecification, like letters on the drawings representin like parts.

The object of this invention is to produce a cheap and effectiveinlet-cock for closettanks; and the invention consists of theconstruction, arrangement, and combination of parts, all as hereinafterdescribed and claimed.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 represents a closet-tank having one of my improved cocksapplied. Fig. 2 represents the cook removed from the tank and enlargedto fully explain its operation and details, and Fig. 3 is a front viewof Fig. 2 and sections on lines R and S.

' A represents a tank of ordinary construction' arranged to support thenecessary appliances for an automatic inlet-cock for closettanks, and Brepresents a pipe bent at right angles, which forms the main part of myim- 0 proved cock for replenishing the tank A with water after it hasbeen drawn off through the wash-valve G. The cock is composed of thismain part B, secured to'the tank at i, the arm B, Fig. 2, and thevertical valve-piston C, oper- 3 5 ated by the pivoted leverD, which isprovided with stem E and float F. The pivoted lever D is secured to thelug B of the cock-frame B by aid of the rivet L, and is operatedvertically by aid of the float F.

The lever D is provided wit-h a recess, I), through which the lower endof the pistonvalve C passes, as shown at D, Fig. This permits the waterto flow uninterruptedly into the tank through the hollow piston-valve 50 (shown at K, Fig. 2) or C'. By this plan I avoid any liability of thewater splattering.

The piston-valve O is provided with lugs, as shown at P, Figs? and 3,which rest upon the side of the lever D at 00 m, Fig. 2. These 5o lugspermit the raising and lowering of the valve 0, while the flattenedsides at 0 prevent its turnin The valve 0 has a seat, R, held to it by ascrew or rivet, and has recesses mcut through it to admit the water intothe interior, and this seat, when the valve 0 is lifted, comes incontact with the inwardly-projecting flange B at the angle of the bentpipe B.

The valve C is provided with packing, N, Fig. 3,which prevents an y flowof water around the lower part of the valve, causing all of it to passthrough the openings on.

The valve 0 is provided with a lug, I, in line with the stem E, and theinterior of the vertical portion of the bent pipeE is recessed to formthe flange U, which is notched at one side, as shown at U at a diameterof the pipe at right angles to the direction of the stem E. hen thevalve 0 is inserted in tube B, it must be turned to bring the flatsurfaces C at right angles to the line of the stem E. This will bringlug U in position to enter notch U Then the valve must be turnedonequarter around to insert the lower end of the tube between the sidesof the lever D. In this manner the flat surfaces 0 hold the valve fromturning and hold the lug U out of line with the recess U so that whenthe water is low the lug will rest upon the flange U and prevent thevalve from dropping out. \Vhen the valve is closed, the recesses m areshut by the wall of the cook, but when opened come down opposite to thegroove H, which, being larger than the diameter of the valve, permitsthe water to flow freely over the valve-top and through the holes 071into the interior of the valve C.

I have not shown the wash-valve lever G, as I have made no improvementsin this part, and consider it too well known to need description.

Having thus described my invention, I claim as new and desire to secureby Letters Patent-- The bent pipe B, formed with the flange Benlargement H, and recessed to form the flange U, having notch U incombination with the hinged lever D, having recess D, and the valve C,flattened at C and formed with lug U, substantially as described.

In testimony whereof I have signed my name in the presence of twosubscribing witnesses.
